Bangpakok 9 International Hospital provides sophisticated Endovenous Laser Treatment (EVLT) for Single-Extremity Varicose Veins, employing modern, minimally invasive techniques and recognised international vascular treatment protocols. 2003 is a JCI, GHA certified hospital located in Bangkok,Thailand, with 300 beds providing vascular care to local and international patients.

EVLT is a minimally invasive procedure that involves using laser energy to treat varicose veins in one leg by closing the affected vein, allowing blood to be redirected through healthier veins. The vascular specialist examines the vein's blood flow and structure using ultrasound before treatment to finalise the treatment choice. Since the procedure is minimally invasive, patients can resume their daily activities relatively fast.
